Pressure as a Source of Gravity

General Relativity and Quantum Cosmology 2009-11-11 v1

Abstract

The active mass density in Einstein's theory of gravitation in the analog of Poisson's equation in a local inertial system is proportional to ρ+3p/c2\rho+3p/c^2. Here ρ\rho is the density of energy and pp its pressure for a perfect fluid. By using exact solutions of Einstein's field equations in the static case we study whether the pressure term contributes towards the mass.
